'lo all whom it may concern:

Be it known that I, CHARLES S. LOCK- wooo, a citizen of the UnitedStates, residing at 289 Market street, Newark, county of Essex, andState of New Jersey, have invented certain new and useful Improvementsin Antitriction-Cagcs for Roller-Bearing Rolls, fully described andrepresented in the following specification and the accompanyingdrawings. 'lorming a partof the same.

This invention relates to an improved means of supporting a movable cagewithin a roller-bearing, so as to guide the rolls in their movement withas little frictional resistance as possible, from the cage itself.

The object is to hold the cage from contact with either the shaft or thecasing,upon either of which dirt is liable to adhere and increase thefriction and resistance to the movement of the same; and this object isattained by supporting the cage wholly upon the flanges fixed at theends of the casing to retain the rolls therein. A rigid cage isnecessary i'or this operation, so as to hold both ends in a concentricpath upon the end flanges, and the cage may be engaged with said flangesby a collar upon either of'the parts, 'ted to an annular recess in theother part The invention will be understood by reference to the annexeddrawing, in which- Figure l is a side view of a bearing embodying theimprovement with the parts in section at the center line where hatched,the cage having a circular collar projected from each of its heads. Fig.2 is a side View of such ca e showing the collars upon the heads; Big. 3is an end view of the cage with dotted lines indicating the rollsadapted to operate therewith; Fig. 4: shows one corner of the casing insection with the. collar upon a the outer edge: of the cage-head; andFig. 5 is an analogous view showing the collar upon the flange at theend the casing instead of upon the cage.

a designates the casing, b the end flanges secured thereon by screws 0and formed with central bore b larger than the shaft (Z to leave anannular recess .0 between each of the flanges and the shaft. The heads7" of the cage are shown connected 1) tie-bars g,

and in Figs. 1, 2 and 3 provide with a col of the cage keeps bothcollars in the proper. I

relation to the recesses.

Fig. at shows a collar 71 formed upon the outer edge of the head insteadof upon the inner edge, as in Fig. 1, the flange b having a groove orannular recess 2 formed therein to receive such exterior collar. Suchengagement of the cage-head with the end flange of.' the casing has thesame effectas the engagement shown in F i 1.

Fig. 5 shows the head f W1thoutany collar, and the flange 6 formed witha collar h adapted to project within the head and to lit the sameloosely enough. for the heads at opposite ends of the cage to ride uponthe two collars, which supports and guides the ca e the same as alreadydescribed.

t is common to use lubricants in rollerbcarings, and it will beobservedthat the parts which form the engagement of the urge with the heads ofthe casing are in such a position as to be automatically lubricated, sothat the collar which guides the cage is enabled to do so with a minimumof frictional resistance.

Having thus set forth the nature of the invention what is claimed hereinis:

'1. The combination, with a roller bearing having a casing with bore tosupport the rolls and a set of rolls to suoport the shaft, of flangesfixed upon the ends of the casing and iuclosin the rolls, and aroll-cage supported nu *aoly upon the said flanges and thereby held fromcontact with the shaft or thcdmre of the casing.

2.- lhe combination, with roller hear ing having a casing witlrjbore tosupportthe rolls and a set of rolls to' en port the shaft, of flangesfixed upon the on s of the cashig each having an annular recess betweenthe my hand in the presence of two sfibscribing smile and the shaft,aandfia rgll-cage ifllaving Witnesses. c0 ars at o osite en s tte to thean es and suppor e d movably in such annular re- CHARLES LOCKWOOD'cesses and thereby held from contact with Witnesses: the shaft and boreof the casing.
